Googong Water Recycling Plant

Project Summary

Project

The Googong water recycling plant is a major component of a 6,200-home greenfield residential development. The plant’s owners wanted a design that used Membrane Bioreactor (MBR) Technology and an integrated water cycle to reduce potable consumption by 62 percent; this would allow the normal water demand of 18,000 residents to be met with the equivalent water use of only 6,500 people. Despite a tight deadline and design challenges including a sloping terrain overlaying rock, it was critical that the project be delivered on time because the treatment plant had to be operational to aid with the construction of the township.

Solution

MWH Global used an integrated design approach, harnessing resources from Sydney, Melbourne, Brisbane, and Pune, India to simultaneously deliver drawings and models with managed version control. Remote collaboration made information mobility vital to the project. Automatic signoffs were used to deliver drawings, models, and i-models to the client on site. The team used 3D modeling from concept through to detailed design to include earthwork, roads, structures, piping, and mechanical equipment.

Outcome

The design team’s plan for the integrated water cycle initiative will reduce the community’s potable water consumption by 62 percent. The 3D model, which was completed on time, helped minimize risk and construction costs by providing valuable information to the construction firm, such as material take-offs, and enabled all stakeholders to identify and address operational, maintenance, construction, and design issues (such as clashes) at the 3D model review stage – before beginning construction.

Software

Bentley software such as AECOsim Building Designer, InRoads, MicroStation, ProjectWise, Navigator, and plant design applications were used to create a 3D model of the new plant and enable information mobility and collaboration across the remote teams. The MWH Global team used the 3D model – enabled by i-models and Bentley Navigator –in review meetings and stakeholder workshops to provide quick and easy identification and resolution of issues, including equipment clashes, dimensional problems, and safety hazards.

Outcome/Facts

The water plant design will reduce the community’s potable water consumption by 62 percent.

By ensuring all operational, maintenance and construction, and design issues were identified at the 3D model review stage, MWH Global met an extremely tight schedule and reduced operational and construction costs.

Construction costs were minimized by using the detailed design data to accurately plan for materials and other construction needs.
